Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a double-shaft mixing device for producing water-based paint. Background Art

[0002] Anticorrosive coatings are generally divided into conventional anticorrosive coatings and heavy-duty anticorrosive coatings, and are an indispensable type of coating in paint coatings. Anticorrosive coatings can be used under harsh conditions and have a long anticorrosive life. Water-based anticorrosive coatings are a type of anticorrosive coating that uses water as a solvent. The application of water-based anticorrosive coatings in the field of heavy-duty anticorrosive coatings is on the rise, such as infrastructure, oil and gas and power industries, as well as industrial tanks, ships and chemical industries. Practical applications have shown that water-based industrial anticorrosive coatings can provide effective protection for steel under extreme conditions. Water-based industrial anticorrosive coatings require mixing of raw materials during production.

[0003] For example, a Chinese utility model patent with authorization announcement number CN218422295U discloses a double-shaft water-based paint mixer that is conducive to uniform stirring, which includes a barrel body, a cover plate is arranged at the opening above the barrel body, a motor is arranged at the center of the upper surface of the cover plate, the output shaft of the motor passes through the inside of the barrel body and is axially connected to a first rotating shaft, and a plurality of first fan plates are arranged on the surface of the first rotating shaft. In the double-shaft water-based paint mixer that is conducive to uniform stirring, the motor is connected to a power source through the first rotating shaft and the second rotating shaft, and the motor drives the first rotating shaft and the second rotating shaft to work. The paint on the edge of the inner wall of the barrel body is stirred by the rotation of the second rotating shaft, so that the water-based paint is stirred more evenly, which is conducive to avoiding the uneven stirring of the paint at the edge of the barrel body, improving the material mixing effect, and greatly improving the quality of the finished paint, thereby greatly improving work efficiency.
